| Sodium TripolyphosphateProperties: White powder;Melting point 622 °C ;Easily soluble in water;It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity . It is a surfactant, and has got outstanding emulsification to lubricants and fat. It has different bulk density, i.e. low density 0.35-0.5g/cm 3 , medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm 3 . This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .Application: Used as one of the main auxiliaries for synthetic detergent, synergist for soap; water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.; As an oil contamination resistance agent in paper production. In foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.Packing and storage: In 25Kg or 50 Kg or 1000 Kg net WPP/PE bags. It must be prevented from moisture and water. Don't pile up in the open air. | | Technical Data | Indexes | Industrial Grade | Food Grade | Assay Na5P3O10 % ≥ | 94.0 | 94.0 | P2 O 5 % ≥ | 57.0 | 57.0 | Water Insoluble Matter % ≤ | 0.15 | 0.05 | Iron(Fe) % ≤ | 0.015 | 0.015 | PH value (1% water solution) | 9.2-10.0 | 9.5-10.0 | Heavy Metal (as Pb) % ≤ | | 0.001 | Arsenic (As) % ≤ | | 0.0003 | Fluoride (F) % ≤ | | 0.003 | Whiteness % ≥ | 90 | 90 | Ignition loss | 1.0 | / | density (g/cm3) | 0.35-0.9 | 0.35-0.9 | Phase I | 10-30 | 10-30 |
